High-Speed Indoor Navigation System based on Visible Light and Mobile Phone

open access: yesIEEE Photonics Journal, 2017
Visible light positioning (VLP) is widely believed to be a cost-effective answer to the growing demand for real-time indoor positioning. However, due to the high computational cost of image processing, most existing VLC-based systems fail to deliver ...

Using Linear Interpolation to Reduce the Training Samples for Regression Based Visible Light Positioning System

open access: yesIEEE Photonics Journal, 2020
We put forward and experimentally demonstrate a second order machine-learning (ML) based visible-light-positioning (VLP) system using simple linear interpolation algorithm to reduce the training samples required in the ML algorithm.

Effects of visible light on mechanisms of skin photoaging

open access: yesPhotodermatology, Photoimmunology & Photomedicine, 2021
Human skin is not only affected by ultraviolet radiation but also by visible light wavelengths emitted by sunlight, electronic devices, and light emitting diodes. Similar to the ultraviolet radiation, visible light has been implicated in photoaging.

Angle-of-Arrival (AOA) Visible Light Positioning (VLP) System Using Solar Cells With Third-Order Regression and Ridge Regression Algorithms

open access: yesIEEE Photonics Journal, 2020
We put forward and demonstrate a angle-of-arrival (AOA) based visible-light-positioning (VLP) system using quadrant-solar-cell (QSC) and third-order ridge regression machine learning (RRML) to improve the positioning accuracy.

Visible Light-Activated PhotoCORMs [PDF]

open access: yesInorganics, 2017
Despite its well-known toxicity, carbon monoxide (CO) is now recognized as a potential therapeutic agent. Its inherent toxicity, however, has limited clinical applications because uncontrolled inhalation of the gas leads to severe systemic derangements in higher organisms. In order to obviate life-threatening effects and administer the gas by bypassing

In a Different Light [PDF]

open access: yes, 2003
This module develops the understanding that visible light is composed of a spectrum of colors of light from red to violet, extends the concept of a spectrum to include non-visible light through discovery, and develops tools and strategies for student ...
